CABLE RAILWAY.

SPECIFICATION forming part of Letters Patent N0.3l5,986, dated April 14:, 1885. Application filed February 3, 1885. (No model.)

To an whom it may concern.-

Be it known that I, WILLIAM WHARToN, J r., a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Gable Railways, of which the following is a specification.

My invention consists of a cable-conduit constructed substantially in the manner described and claimed hereinafter, for the purpose of adjusting the side or sides of the conduit and maintaining the slot at a suitable width.

In the accompanying drawings, Figures 1 and 2 are transverse sections of conduits made according to my invention, and Figs. 3, 4, 5, and 6 sections illustrating modifications.

In Fig. 1 the conduit A, which may be varied in shape without departing from my invention, is secured to or rests in frames B, which are arranged at suitable distances apart,

' the slot being bounded at the top by the bars c a, of rolled steel, commonly called slotbars, one bar being attached to one side and the other to the opposite side of the conduit. Each frame has extensions 6 I), to afford anchorages for the outer ends of the adjustable stay-rods D, the inner ends of which are connected one to one side and the other to the opposite side of the conduit.

The rods may be made adjustable by right and left hand screw-couplings, or by any other available adjusting devices, the object being to increase or diminish the width of the slot, as circumstances may require that is to say, the rods can be used to draw the upper portions of the conduits apart, the pressure upon the sides of the conduit forcing the same together when the nuts on the rods are slackened.

Although I prefer stay-rods on both sides of the conduit, this is not essential, for the width of the slot may be increased or diminished by adjustable connections on one side only.

The invention is allied to that for which Letters Patent No. 281,593 were granted to me July 17, 1883, and also to the devices described in applications A, B, O, and D, bearing even date herewith, in all of which cases adjustable stay-rods are used to determine the width of the slot of the conduit, as in the present instance; but in all of the above cases the stayrods connected to the conduit are anchored outside, away from and independent of the same, while in my present invention they 5 are anchored to attachments or extensions of the conduit.

The invention may be carried into efi'ect in different ways-for instance, in Fig. 3 I have shown how the adjusting-rods D may be eonnected to attachments b b, secured to the sides of the conduit. In Fig. 4, bars B B simply abut against the sides of the conduit, and may be considered attachments or extensions of the same, D D being the adjustable stay-rods. 6 5 Reliance may be placed upon the superincumbent pavement and soil for maintaining these bars in position, or they may be confined with diagonal stay-rods s .9, attached to the conduit, as shown by dotted lines.

In Fig. 5 I have illustrated a mode of applying my invention to the plate-iron conduit for which Letters Patent were granted to A. Bonzano, No. 287,220. In this case, also, the structure contains within itself the means of ad- 7 5 justing the conduit and determining the width of the slot. Inclined compression members I I,which may be of channel-iron or other bars possessing the necessary rigidity, have their hearings in the corners at the junctions of the Sc sides of the conduit with the beam H, tensionrods w w connecting the beam to the outer ends of the bars, which are connected to the sides of the conduit by the adjustable rods D D. Substantially the same mode of carrying out my invention is shown in Fig. 6, where webs or plates I I, secured to the sides of the conduit and to the beam H, are substituted for the compression-bars I and tension-rods w.

Other modifications embodying my inven- 0 tion will readily suggest themselves to expert mechanics.

It has not been deemed necessary to show in detail the modes of making the connections of the several parts, as these may be varied In testimony whereof Ihave signed my name 10 according to the judgment of the constructer. to this specification in the presence of two sub- I claim as my inventionscribing Witnesses.
